Caryl Phillips’s multi-voiced texts have often been studied through the lens of Bakhtinian polyphony. In this essay, I focus on the volume of fictionalized biographies Foreigners: Three English Lives (2007) to demonstrate that the polyphonic nature of Phillips’s work resides not only in the structural confrontation of characters’ and narrators’ voices but also in the inscription of the writer’s own subjectivity within these individual discourses. Borrowing methods from the discipline of stylistics, I first focus on the use of adjectives and modality in the opening section of Foreigners, “Dr. Johnson’s Watch,” to establish how the first-person narrator’s gradual transition from tentativeness to self-confidence constitutes a way for the implied author, on the one hand, to expose the thwarted logic of the colonially-tinted discourse of his eighteenth-century narrator and, on the other, to offer larger reflections on the process of ideological encoding inherent in the writing of historiography. Such an investigation based on modality furthers allow me to challenge the critical consensus according to which the second section of the book, “Made in Wales,” is a straightforward factual account. Indeed, I suggest that the story of the rise and fall of mixed-race boxer Randolph Turpin is in fact a highly polyphonic narrative featuring increasingly marked clashes in modality and point of view. These, I argue, may draw attention precisely to the problematic construction of historiographical discourse deceptively made to appear so commonsense by the narrator of “Dr. Johnson’s Watch.” [less ▲]

Road remains the most used mode in Europe. Even if it is appreciated for its responsiveness, flexibility, and quickness, road transport is however responsible for negative impacts on its environment like air pollution or climate change. Intermodal freight transport i.e. the transportation of goods using two or more modes of transport, in the same loading unit, without handling of the goods themselves is identified by the European Commission as an interesting solution for limiting the negative impacts of transport. In the classical conception of intermodal transport, pre- and post-haulage travels are supposed to be short, and to be performed by road transport, whereas the long-haul travel is done using rail or inland waterways (IWW). The objective of this study is to determine the impact on intermodal attractiveness of allowing other combinations of modes than the classical road-rail/IWW-road combination, during an intermodal travel. The goal is to determine the flow distribution of goods between direct transportation by road, rail or IWW, and any combination of these modes using intermodal transport. The novelty consists in taking into account three modes of transport in a mixed integer programming model, and to allow the transfer from any mode to any other at intermodal terminals where these modes coexist. For testing the hypothesis of intermodal transport attractiveness on medium to long distance, the model is applied to experimental data at the European level. [less ▲]

The Westerwald region is one of the largest and oldest clay mining areas of Germany. Those deposits were formed during the Eocene and Oligocene as a result of the weathering, erosion and redeposition of Devonian rocks. During the Miocene, intense volcanic activities led to a large basalt cover, protecting the clays from the erosion. The two main goals of this study are first to improve the knowledge on the weathering processes of the Devonian slates that led to the current setting of those clay deposits by studying the mineralogical and chemical composition of the clays with depth. The second goal is to characterize a bentonite layer underneath the Miocene basalt cover using quantitative X-ray diffraction, chemical analysis, BET, cation exchange capacity and scanning electron microscope. A 20 meter deep quarry mining the Devonian bedrock in southern Westerwald has been sampled on its entire depth. The XRD results show no significant variations of the mineralogy with depth, except for the phyllosilicates. The minerals of the < 2 μm fraction are illite, kaolinite, smectite and mixed-layers minerals (vermiculite-chlorite and illite-chlorite). The proportions of the minerals in the mixed-layers chlorite-vermiculite vary with depth. At the bottom of the quarry, the proportion of vermiculite is very low while in the top, the proportion of vermiculite is higher. This is explained by the degree of the weathering, logically more intense at the top of the quarry. Trace elements compositions are currently being investigated. A 3 meter thick greenish to brownish bentonite layer has been found in the eastern part of the Westerwald region. The XRD performed on different samples of this bentonite shows a relatively heterogeneous composition: montmorillonite (60-80%), kaolinite (5-12%), illite (0-7%), goethite (2-15%), talc (0-10%), K-feldspars (0-7%), plagioclase (0-4%) and traces of amphibole and pyroxene. This bentonite is probably the result of the weathering of volcanic ashes. Since there are not many outcrops of this bentonite layer, its spatial distribution is studied by drilling. [less ▲]

Drawing on the analysis of statistics regarding Intimate Partner Violence collected on a large scale at the level of the Belgian prosecutors’ offices, the article reveals a wide gap between the zero tolerance rhetoric conveyed in the normative discourse and actual implementation, which is generally weak and showing divergent judicial practices in the field. Faced with this dilemma, the highly contestable impact of the zero tolerance policy observed in preventing recidivism offers a substantial argument to revisit the role of the criminal justice system in this area.

Introduction To be a firefighter is a dangerous job. Many authors have found anxiety, stress, depression, sleep disorders, absenteeism and other deviant behaviors in this type of high-risk occupation (Fullerton, Ursano & Wang, 2004 ; Carey, Al-Zaiti, Dean, Sessanna & Finnell, 2011 ; Elliot & Kuehl, 2007). Adopting an active lifestyle is therefore very important in reducing these health risks and thus maximizing the chances of staying healthy. It is for this reason that physical activity has an essential role for these people. According to this determining the place occupied by physical activity within the regional Walloon fire servicesseemed relevant. The first step should be to analyse the firefighters’ representations and lifestyle. Methods An online questionnaire (SurveyMonkey) was developed. It proposed a majority of closed-ended questions facing on age (38 ± 10.4 years), BMI (26.1 ± 3.7), gender (96.7% of men), rank, status (38.3% professional), PA representations and practices, well-being and self-esteem, job satisfaction, … We contacted one of the main firefighters association (FRCSPB) to reach a significant number of topics. 443 questionnaires were collected during a five weeks period. 394 were usable. 376 responses were needed to achieve a 95% confidence level with a 5% confidence interval based on all Belgian Firefighter. Results and discussion Results showed that firefighter showed positive representations about PA and were aware of the benefits of a regular practice on their health. Good stress management and cardiovascular endurance qualities were considerate as important in this profession. Nevertheless, subjects deplored a lack of maintenance of these qualities. The mean BMI of the subjects was above 26, indicating a slight overweight. Sedentary lifestyle, poor infrastructure, injuries due to lack of fitness allow us to suspect an insufficient training. Other factors were pointed out by the subjects (stress, absenteeism, deviant behavior…). Firefighters were generally satisfied with their job and considered that they have an acceptable quality of life. However lack of time, financial and human resources must not be a barrier to the practice of essential PA for those people who are directly related with danger. References Carey, M. G., Al-Zaiti, S.

Analogical reasoning shares a mutual influence with language development: analogical reasoning is improved by labelling analogical items with words describing the relations that they contain. Conversely, structural alignment, a core mechanism of analogical reasoning, allows the acquisition of novel words and the development of grammar (Gentner, 2010). Given those findings, some authors have taken interest in the analogical reasoning ability of children with language disorders, and specifically of children with Specific Language Impairment (SLI). Those children have worse performance than their age-matched peers without language disorders in linguistic or non-linguistic analogical tasks (Leroy, Maillart, & Parisse, 2014). Our aim here is to see if this weakness is due to their language disorders and if they use the same verbal strategies as their peers to solve an analogical task. To experience these assumptions, we use a perceptual analogical task following an A:B::C:D paradigm: participants have to find the relation between two geometric forms A and B and to apply it to the C term in order to find the D term among distractors. The distractors either share perceptual features with the C term, what creates a competition that shall be inhibited, or not. Moreover, children are faced with three interfering task conditions: one without any interfering task, one with an articulatory suppression secondary task and one with a tapping secondary task, which is used in order to measure the general dual task demands. Comparing the results of these conditions will allow us to evaluate the impact of language and verbal strategies on analogical reasoning in control and SLI children. [less ▲]

Recent studies have shown that agency plays an important role in the desistance process. This variable allows the transition from delinquent identity to non-delinquent identity. However, despite increasing literature about this topic, there is a lack of consensus regarding the role of this variable in the desistance process. Also, the way to measure this phenomenon remains unclear. In our study, agency is thought within a border framework, namely the understanding of all kind of behavior. According to the social cognitive theory, emotional and cognitive processes influence human behavior: emotions and thoughts that will define ways of acting and will motivate behavioral changes. Outcomes expectancies can be help or hinder for the concretization of behavioral change. We conducted a qualitative research among adolescents (aged 17-18) who are engaged in a delinquent trajectory. Our objective are to understand how these young in transition to adulthood leave delinquent lifestyle by evaluating to their life course and delinquent course. Each participant was interviewed with a semi-structured interview. To ensure that the interviews provided rich insights into participants’ reality, the interview was designed to elicit detailed information on relevant themes including identity, turning point, future and delinquency trajectory. Desistance was not explicitly questioned. All interviews were taperecorded and analyzed using IPA method (Smith, 2003). Mastery Scale (Pearlin, 1978), Causal Attribution Scale (Rossier, 2002), Hope Scale (Snyder, 1991) and University Rhode Island Change Assessment Scale (McConnaughy, 1983) were also administered. We see that the younths interviewed are at different stage in their desistance process. All of them, persistent or desistant, consider taking a hold on their lives. These results encourage thinking agency in the understanding of all kind of behavior. We should then take into account the beliefs and expectations of results as a variable mediating the relationship between agency and desistance. [less ▲]

Since the turn of the century, the study of popular music has become one of the hottest topics in French Universities. Of the 71 existing institutions, nearly all of them have one or another official expert on that question. But between the study of a national or an international heritage, between scientific disciplines and humanities, researches devoted to popular music seems to be as perennial as fragmented. My paper will aim to present the evolution of recruitment in this area. Which disciplines were the most active in those recruitments and, beyond these raw numbers, what does it mean ? Why is the French academic situation so different to that of Italy for example ? What are the challenges of this academisation ? Which topics are taught under this heading ? I’d like to show that next to the objective reasons of this disciplinary interest, there are also various institutional issues that seems to correspond exactly to the assumptions of Bruno Latour (La science en action, 1989) and Edward Slowik (Structure of Musical Revolutions, 2007).

Drug trafficking is a mounting security problem in Latin America, specifically for the primary producers of narcotics in the region: Mexico and Colombia. The security concern from both countries has triggered the political and social mobilization of Mexican and Colombian migrants from abroad many of them from the Global City of Brussels. This paper unpacks the motivations and dynamics behind transnational political activism organized by Mexican and Colombian women living in Brussels. By integrating and revising insights from social movements theories, political transnationalism from migration studies and intersectionality studies, this paper elaborates on the role of migrant women organizing and sustaining transnational political movements to change the political conditions of their countries of origin. The ethnographic evidence presented in this paper reveals the importance to recognize the individual level in the analysis of transnational movements. Women are cognitive actors with political ideals and emotions whose political activism is highly influenced by social categorizations such as gender, race, class, and generation. [less ▲]

The purpose of this study is to characterize the clay raw materials being exploited and used in the earthenware sector (pottery and building materials) of Marrakech region. It aims to improve product quality in 12 sites within a radius of 10 to 80 km around the city of Marrakech, where are active more than 850 potters spread over about 550 workshops. This characterization also aims at establishing a database on the properties of the raw materials of Marrakech and on the characteristics of the products. This will help in the selection of the most suitable materials, which generate the least defects, in restoring the historical sites of the city and in linking archaeological ceramics with their possible source of clayey material. A total of 34 samples of clay raw materials were collected from the various studied sites. 26 ceramic pastes were formed from these raw materials. Ceramic pastes have been characterized for their particle size (semi-wet sieving and laser particles size), chemical (XRF) and mineralogical compositions (XRD), plasticities (Atterberg limits), carbonate content (Bernard's calcimetry), drying behaviour (Bigot curve) and loss on ignition. The fired products were characterized by firing shrinkage, water porosity, compressive and flexural strengths and by SEM combined with EDX. The studied ceramic pastes show a large particle size variation: clay (18-66%), silt (12-53%) and sand (5-65%). Mineralogically, they are composed mainly of clay minerals (25-60%), quartz (20-55%), feldspars (5-35%), carbonates (≤15%), diopside (5-10%) and hematite (1-3%). Clay minerals are formed by illite (10-40%), kaolinite (5-15%), interstratified (≤10%), talc and pyrophyllite (≤10%), vermiculite (5%) and chlorite (≤5%). The chemical composition shows that the majority of the pastes are composed of SiO2 (48-74%), Al2O3 (12-20%), Fe2O3 (3-8%), CaO (0.4-8%), K2O (2-5%), MgO (0.5-3.5%), Na2O (0.1-2%), TiO2 (0.8-1.2%), P2O5 (≤ 0.4%) and MnO (≤ 3%). Plasticity varies from one paste to another with plasticity indices between 15 and 32. The shrinkage on drying is between 4 and 10%. For a firing temperature of 1050°C, the firing shrinkage of the various pastes is between 0.5 and 5%. The mineral transformations during firing are very diversified from one sample to another and from one site to another. The comparison of the obtained results shows that granulometry, mineralogy and degree of diagenesis are the main factors controlling plasticity. We showed a relationship between the properties of the pastes (particle size, mineralogy and plasticity) and the type of product. We proposed solutions for each of the many observed defects (poor quality of raw material, lime blowing, lime efflorescence, inadequate drying procedure, cracking, blisters, black hearts, crazing and poor ovens quality). In addition, this study valuated the clay raw materials of the Marrakech region for the use in the field of production of building materials. [less ▲]

Rapid industrial development and intensive agriculture induced serious soil degradation in recent decades worldwide and specifically in China. In cropland, soil acidification and nutrient deficiency are often associated with increased use of nitrogen (N) fertilizers. Soil acidification can lead to reduction of phosphorus (P) availability, even though with high inputs of P fertilizer. The studies presented in the thesis deal with spatio-temporal evolution of soil pH in different soil types and land uses in southern China and effects of soil acidification on soil P availability. Evolution of inorganic P fractions in Red Soil was characterized upon fertilization trials, as a response to long-term fertilization and soil acidity changes. The first focus of the thesis deals with spatio-temporal evolution and main factors of soil acidification in different soil types, parent materials and land uses of Southern China. Firstly, data from 20 monitoring sites under 25-year fertilization on Paddy Soil were investigated to research changes of pH. Paddy Soil pH significantly declined from 1988-1998, then stabilized from 1998-2013 with conventional fertilization. Chemical N fertilization, manure application, soil available N and total N increases were significantly correlated with soil pH. Secondly, changes of pH in Red Soil and Paddy Soil were assessed in 32 monitoring sites of Hunan Province (Southern China) under 10-year fertilization in order to analyze soil acidification in different soil types and agro-systems. Soil pH decline was observed in Paddy Soils under rice-vegetable rotation but not observed in Paddy Soil under continuous cropping with rice. Soil pH significantly declined in Red Soil with high initial soil pH. Thirdly, spatio-temporal characteristics of soil pH were investigated by comparison of soil pH between 1982 and 2014 in Qiyang County (Hunan Province). Average topsoil pH declined of 0.58 units between the two surveys. Soil pH in the south was lower than in the north both in 1982 and 2014. Land use and parent materials are the main drivers of differences in the soil pH changes in Qiyang County. Soil pH declined significantly in forest and upland crop over non-alkaline parent materials during 1982-2014 period. Chemical N fertilizer application can have generated 12-42 kmol H+ ha-1yr-1, which is much higher than removal by crop harvest. Reduction of chemical N fertilization and return of straws to field should be conducted to reduce H+ production and supplement base cations in Qiyang County. The second approach studied evolution of inorganic P fractions in Red Soil under 25-year fertilization, and available P and inorganic P fractions responses to various soil acidity levels. Inorganic P fractions increased under P fertilization from 1990-2015, especially Ca2-P, Ca8-P and Al-P, but inorganic P fractions significantly decreased without P fertilization. Contributions of soil properties (SOC, C:P ratio and N:P ratio) and cumulative P apparent balance (CPAB) to inorganic P fractions were ≥ 95%, while interaction of CPAB and soil properties made greater contributions than did any single factor. Soil dissolved inorganic P (DIP) decreased with rising pH value, and a minimum DIP was observed between pH 5.5 and 6.5. Olsen-P, Ca-P and Al-P increased significantly with pH between 3.4 and 5.0. Soil with pH <5.0 P availability was much lower than soil with pH ≥5.0. Managing soil acidity is a key issue regarding availability of P in Red Soil of China and our results suggest that at least a pH of 5.0 should be targeted. [less ▲]

Abscission is the mechanism by which plants disconnect unfertilized flowers, ripe fruits, senescent or diseased organs from the plant. In tomato, pedicel abscission is an important agronomic factor that controls yield and post-harvest fruit quality. Two non-allelic mutations, jointless (j) and jointless-2 (j-2), controlling pedicel abscission zone formation have been documented but only j-2 has been extensively used in breeding. J was shown to encode a MADS-box protein. Using a combination of physical mapping and gene expression analysis we identified a positional candidate, Solyc12g038510, associated with j-2 phenotype. Targeted knockout of Solyc12g038510, using CRISPR/Cas9 system, validated our hypothesis. Solyc12g038510 encodes the MADS-box protein SlMBP21. Molecular analysis of j-2 natural variation revealed two independent loss-of-function mutants. The first results of an insertion of a Rider retrotransposable element. The second results of a stop codon mutation that leads to a truncated protein form. To bring new insights into the role of J and J-2 in abscission zone formation, we phenotyped the single and the double mutants and the engineered alleles. We showed that J is epistatic to J-2 and that the branched inflorescences and the leafy sepals observed in accessions harboring j-2 alleles are likely the consequences of linkage drags. [less ▲]
